Benjamin - I assume you are referring to the drive belt that runs from the front PTO, through the mule drive, and onto the drive pulley of the deck. It's not too difficult, but you really need illustrations to explain the procedure due to the belt path through the mule drive. I also assume you don't have a manual for the mower deck, since that is where the instructions are listed. What size deck do you have? If I have the same size, I might be able to e-mail you some information. - Dave
